Changing field names via the `names` attribute. AFAIK, the other attributes in dtypes are not mutable, and mutability was added long ago as a workaround for `.view()` not handling name changes properly. There's possibly some code out there that touches the `names` attribute, so it's not clear if this can be fixed in the 1.x series. -- Pauli Virtanen _______________________________________________ NumPy-Discussion mailing list [email protected] http://mail.scipy.org/mailman/listinfo/numpy-discussion
